  In the conventional bathtub 1 with a vertically long grip, the arm of the user Mb who wants to change the body direction for changing the left-right position in the bathtub or the like is moving in the left-right direction along the vertical surface 2a in the tank. The outer surface 3c of the vertically long grip 3 is moving while the knee of the user Ma bathing in the sitting posture in contact with the outer surface 3c of the vertically long grip 3 or bending the knee is moving along the standing surface 2a in the tank. Or may come into contact with. In this case, the user Mb is often in a state in which the contact surface such as an arm is inclined with respect to the front-rear direction. This often causes local contact with the separated edge 3c-1, which causes pain and discomfort.

  An object of the present invention is to provide a bathtub with a vertically long grip that can alleviate the degree of pain and discomfort that occurs when a user comes into contact with the vertically long grip.

  The means employed by the present invention according to claim 1 to relieve the pain and discomfort of the user that occurs when abutting the vertically long grip is provided by connecting the upper and lower connecting portions of the vertically long grip to the vertical surface of the bathtub. In a bathtub with a vertical grip, the vertical grip extends from the long grip on the front side, which is long in the vertical direction, to the rear, and the vertical grip is the left and right extending from the grip to the upper and lower connections. Each outer surface is inclined so that the left-right width dimension from the virtual vertical center plane passing through the left and right middle of the left and right outer surfaces in the up / down / front / rear direction to each outer surface becomes smaller as going from the rear to the front. This is a bathtub with a vertically long grip.

  In order to reduce the pain and discomfort of the user that occurs when contacting the vertically long grip, the means adopted by the present invention according to claim 2 is provided by connecting the upper and lower connecting portions of the vertically long grip to the vertical surface in the bathtub. In the bathtub with a vertical grip, the vertical grip extends along the vertical direction of the vertical surface in the bathtub. When viewed from the upper side to the lower side, the outer angle between the left and right outer surfaces extending from the grip part to the upper and lower connection parts and the joint surface of the connection part joined to the bathtub body exceeds 120 ° and is 120 ° or less (preferably Is a bathtub with a vertically long grip, which is selected in a range of more than 93 ° and not more than 98 °.

  In order to further reduce the degree of pain and discomfort of the user that occurs when abutting the vertically long grip, the means adopted by the present invention according to claim 3 is characterized in that the left and right outer surfaces of the vertically long grip are vertically moved. 3. A vertically long grip according to claim 1 or 2, wherein the longitudinal grip is curved so as to be continuously dented toward the virtual vertical center plane passing through the left and right middle of the left and right outer surfaces up and down and forward and backward as going from the end to the vertical center. It is a bathtub.

  The bathtub with a vertically long grip according to the first aspect of the present invention is configured so that the left and right outer surfaces of the vertically long grip become smaller in the left-right width dimension from the rear toward the front. When the abutment surface of the user's arm, etc., which is inclined with respect to the front-rear direction as well as the outer surface of the vertical grip, contacts the outer surface of the vertical grip, the surfaces of the inclined surfaces are inclined. The contact force per unit area can be reduced by contact, and the user's contact surface is guided by the outer surface of the vertically long grip and moved forward to facilitate escape from the vertically long grip. The degree of discomfort can be reduced.

  The bathtub with a vertically long grip according to the second aspect of the present invention has an outer angle between each of the left and right outer surfaces and the joint surface of the connecting portion joined to the bathtub body of more than 90 ° and 120 ° or less (preferably 93 °). Since the left and right outer surfaces are inclined with respect to the front-rear direction, the user is inclined with respect to the front-rear direction in the same manner as the outer surface of the vertical grip. When the abutment surface of the arm or the like abuts the outer surface of the vertical grip, the contact force per unit area can be reduced by the surface contact between the inclined surfaces, and the user's contact surface is guided by the outer surface of the vertical grip. And since it can move to the front and it is easy to escape from a vertically long grip, the degree of pain and discomfort can be relieved compared with the past.

  In the bathtub with a vertically long grip according to the present invention as defined in claim 3, when the contact surface of the user's arm or the like is in contact with the left and right outer surfaces of the vertically long grip, the area in contact with the outer surface curved so as to be recessed is Compared to the case where the left and right outer surfaces of the vertically long grip are made straight without bending, the degree of pain and discomfort can be further alleviated. Moreover, although the user who goes in and out of the bathtub may hit the head on the curved portions of the left and right outer surfaces, the contact area increases at this time, and the degree of pain and discomfort can be further alleviated.

  A bathtub with a vertically long grip according to the present invention (hereinafter referred to as “the present invention bathtub”) will be described based on an embodiment shown in the drawings.
